The fonds consists of correspondence, photographs and artwork. There are three letters associated with Clingan: one letter he wrote as a child to his father, one letter from A. Clingan that discusses him during World War I, and a third letter from a pal of his written on 9 January 1916. There are sixteen letters written by his son-in-law Lt. Colin Murray to his wife from Hannover in 1953. Graphic material includes a portrait of Clingan during World War II taken in Kirkgate, Yorks. and a caricature of him (pencil, ink, water-colour) at Aldershot in 1941. There are photographs of the Cameron Highlanders of Ottawa in 1940 and 1942; the Stoney Creek Band; the 260th Barracks, 2nd River; a Canadian troopship bound for Siberia; picture postcards of Vladivostock, and unidentified military photographs. Most of the photographs were removed from frames – numbers are written on the verso but their meaning is not known. Also in the fonds is a photograph of Queen Elizabeth, the Queen Mother, at a military base, a kilt pin, printed “Returned Soldiers’ Insurance” certificates issued to Clingan in 1930, and a printed issue of the Cameron Highlanders’ Journal from 1939. Clingan’s medals were sold at Bonhams in May 2009 and do not form part of this fonds.
